We meet the same error and solved it by setting Path of environment variables on Windows / Linux (LD_LIBRARY_PATH) / MacOS (DYLD_LIBRARY_PATH). For example:

1. Our environment:
   • ASP.NET Core v3.1
   • IBM .NET Core 3.1 / EntityFrameworkCore 3.1 in v11.5.4
   • IIS 8.5
   • Windows Server 2012 R2 (64 bits)
2. In web.config, we add the <environmentVariable name="Path" value="C:\Users\Administrator\.nuget\packages\ibm.data.db2.core\3.1.0.200\buildTransitive\clidriver\bin" />.

   <?xml version="1.0" encoding="utf-8"?>
   <configuration>
     <location ... >
       <system.webServer>
   
         ...
   
         <aspNetCore ... >
           <environmentVariables>
             <environmentVariable name="Path" value="C:\Users\Administrator\.nuget\packages\ibm.data.db2.core\3.1.0.200\buildTransitive\clidriver\bin" />
           </environmentVariables>
         </aspNetCore>
       </system.webServer>
     </location>
   </configuration>
   

3. Set folder permissions (Read & Execute, Read, and List Folder Contents) for Application Pool Identity Accounts (IIS AppPool\[App_Pool_Name])
